FAQ

Common questions about Vendel. Still confused? Open an issue or ask on Telegram.

Is Vendel really free?

Yes. Vendel is open source and free to self-host. You only pay for your own infrastructure (server, SIM cards, etc). No per-message fees, no hidden costs.

What devices can I use?

Any Android phone with a SIM card works. We also support USB modems. The older the phone, the better — repurpose that drawer full of old phones.

How many messages can I send?

The hosted version at vendel.cc has quotas per plan: Free gets 50 SMS/month, Hobby gets 500/month, and Pro gets 5,000/month. Self-hosted has no limits — send as many as your carrier allows.

Is there a hosted version?

Yes! It's live at vendel.cc. There's a free tier with 50 SMS/month to get started. Paid plans start at $0.99/month if you need more capacity.

Can I use this for marketing/bulk SMS?

Technically yes, but please don't. Vendel is designed for transactional messages: OTPs, notifications, alerts. Carriers will block you if you spam.
